CFE bootloader for BCM4908 uses custom image format. It consists of:
1. Optional cferom image
2. bootfs JFFS2 partition (cferam, kernel, DTB and optional helper files)
3. padding
4. rootfs simply appended to the bootfs + padding
5. tail with checksum and basic device info
This util allows creating, modifying and extracting from BCM4908 images.
